Diffusion-weighted imaging (DWI) can depict small punctate hyperintense lesions in the hippocampus transient global amnesia (TGA). The purpose of this study was to find an optimal DWI protocol for lesion detection TGA by investigating various parameters and timing after symptom onset.Sixteen patients with diagnosed during 14 months underwent within 24 hours again at follow-up 3 days onset. Each session included 4 different sequences using b-values (seconds per square millimeter) section...
BACKGROUND AND PURPOSE: Intracranial solitary fibrous tumors (ISFTs) are rare mesenchymal neoplasms originating in the meninges. The aim of this study was to describe CT, MR imaging, and angiographic features tumor identify imaging characteristics. MATERIALS METHODS: We retrospectively reviewed MR, findings 6 cases ISFT. evaluated size, shape, location tumor; internal content margin lesion; pattern enhancement; change adjacent structures. Density on noncontrast CT scans, signal intensity...
Background Persistent primitive trigeminal artery (PPTA) is the most common permanent carotid-basilar anastomosis. Magnetic resonance angiography (MRA) has become primary non-invasive imaging technique for evaluation of cerebral vascular anatomy and can provide detailed 3D intracranial vessels. Purpose To evaluate usefulness MRA detection PPTA to re-classify its variations based on embryologic types PcomA relationship with basilar branches. Material Methods Of total 7329 patients who...
<h3>BACKGROUND AND PURPOSE:</h3> Although MR imaging is considered the most effective method to confirm a diagnosis of WE, studies designed distinguish WE between NA and AL patients have yielded controversial results. The purpose this study was determine potential differences in features with compare neurologic symptoms findings. <h3>MATERIALS METHODS:</h3> This retrospective included 24 consecutive (male/female, 15:9; mean age, 54 years) diagnosed university hospital (AL = 13, 11). Clinical...
Therapeutic hypothermia (TH) improves the neurological outcome in patients after cardiac arrest and neonatal hypoxic brain injury.We studied safety feasibility of mild TH with poor-grade subarachnoid hemorrhage (SAH) successful treatment.Patients were allocated randomly to either group (34.5°C) or control clipping coil embolization.Eleven received for 48 hours followed by slow rewarming.Vasospasm, delayed cerebral ischemia (DCI), functional outcome, mortality, profiles compared between...
To evaluate the effectiveness and safety of a new liquid embolic agent in preoperative portal vein embolization.Embol-78 was obtained by means hydrolysis polyvinyl acetate dissolved mixture ethanol nonionic water-soluble contrast medium. After percutaneous puncture vein, embolization right performed 22 patients with hepatocellular carcinoma 29 nonhepatocellular carcinoma. In each group, changes volume future liver remnant, venous pressure, enzymes were evaluated both before after...
<b>BACKGROUND AND PURPOSE:</b> Rhabdoid meningioma (RM) is a recently described variant of malignant meningioma, with radiologic features currently not well characterized in the medical literature. The purpose this study was to describe and characterize clinical imaging findings associated RM. <b>MATERIALS METHODS:</b> CT (<i>n</i> = 8) MR 15) images 15 patients (4 men 11 women; mean age, 52 years; range, 22–75 years) 16 pathologically proved RMs along records were retrospectively reviewed....
The embryonic tentorial sinus regresses at the 60–80 mm embryologic stage and most of deep venous channels constitute basal vein Rosenthal (BVR). Persisting remnants can be seen in adult configuration BVR. We tried to explain anatomic representations BVR associated with remnant sinus. A total 41 patients 82 hemispheres were included this study. CT angiography was performed all as screening for cerebrovascular disease or other intracranial disorders. separate workstation 3D software used...
A Case of Atypical Skull Base Osteomyelitis with Septic Pulmonary EmbolismSkull base osteomyelitis (SBO) is difficult to diagnose when a patient presents multiple cranial nerve palsies but no obvious infectious focus.There report about SBO septic pulmonary embolism.A 51-yr-old man presented our hospital headache, hoarseness, dysphagia, frequent choking, fever, cough, and sputum production.He was diagnosed having masked mastoiditis complicated by palsies, sigmoid sinus thrombosis, embolism.We...
In this study, the diagnostic value of Tc-99m hexamethylpropylene amine oxime (HMPAO) leukocyte scans and role additional SPECT in diagnosis bone infection were evaluated.The HMPAO 37 patients with clinically suspected reviewed. The divided into two groups according to presence orthopedic implants. Early (4 6 hours) delayed (18 20 planar images early obtained. final was made based on pathologic, bacteriologic, surgical data clinical follow-up.Group 1 (25 implants) included 15 true-positive,...
